'I'he article which I have devised consists generally of a flexible, pliable, cushion which is preferably a ribbon or ply of felt I that is protected by a sheet 2 of suitable water-proofed fabric. The longitudinal edges of the fabric may extend to one of the edges of the felt and the parts are maintained in position preferably by a row of stitches, staples, or the like,designated as 3, or in any other suitable manner. The strip may be slightly stiened by employing a strip of reinforcement 4 that is disposed along one of the longitudinal faces of the felt cushion between the latter and the covering or rrotecting fabric or between two plies of the cushion material. The reinforcement may be any suitable material that will tend to add a degree of stiffness that may be desired in a device of this character. A material that is effective for this purpose is woven fabric such as burlap, canvas or the like that may be treated with sizing or adhesive. The reinforcement of the sponge rubber may be omitted, for example, as shown in Fig. 17.

The protecting material does not extend entirely around the exible pliable material and is preferably omitted along one of the longitudinal edges. In Figures 14 to 18 the covering material 2 extends across the wide faces of the cushion and around one edge, but is omitted around the opposite edge indicated by the numeral 6. The stitches or other securing means 3 pass through the protective covering material as well as the cushion in a line adjacent the exposed edge 6, and the cushion may be without reinforcement as shown in Figure 14, or may be provided with the reinforcement 4 as shown in Figures 15 and 16. Also the cushion material may be either felt, as shown in Figures 14, 15 and 16 or it may be sponge rubber 5 as shown in Figures 17 and 18 and in the latter event the sponge rubber may be provided with the reinforcement 4 as shown in Figure 18. The several structures shown in Figures 14 to 18 are adapted lto be inserted edgewise into a groove or a channel piece 'I (Fig. 14) which m'ay be either wood or metal and may be either a separate piece or may be a part of the doorway, window or venti- Aure 1 the strip of felt cushion I is wider than that shown in Figures 14 to 18, and it is provided with a longitudinal fold as at Ia after which the protective cover cloth 2 is placed around the looped portion thereof.

The free longitudinal edges of the cushion and covering fabric are disposed parallel to each other and they are held in compressed relation by means of a metal strip that is so shaped in crosssection that it will bind or clamp the parts to-l gether. The metal strip is formed with a channel or seat 8, one of the arms 9 of which is curved inwardly towards the other arm I0, the latter being wider than the arm 9. At a location about opposite the lower edge of arm 9, the arm I is provided with an outwardly extending bead or rib I I and said arm thereafter extends downwardly in a substantially dat portion I2, which is slightly bowed inwardly at its lower edge'as at I3. The lower edge of arm 9 is disposed opposite the shallow recess formed on the inside of the bead I I and when the two arms are pressed towards each other with the cushion and cover fabric between them the latter will be compressed in the manner shown and will be firmly held in position. The metal strip is preferably utilized in nailing the weather-strip upon the door or window in the usual manner.

In Figure 2 the felt cushion is provided with reinforcement or stiffening material 4 upon one surface, preferably the surface that is folded against itself in forming the loop, so that the stiifening material is also formed into a loop in the same manner as the felt cushion. In Figure 3 the reinforcement 4 is disposed within the body of the felt cushion material between the respective faces thereof.

As has been hereinbefore stated, the cushion material, instead of being of felt may be a sponge rubber. Such substitution is shown in Fig. wherein the'sponge rubber 5 forming a cushion is looped in the same manner as the felt is looped in Figure 1, and the sponge rubber loop is provided with the covering, the whole structure then being pinched together between and by means of the arms of a metal strip as previously described. In this type, as well as in the other types, the cover fabric may be loose, or it may be secured to the cushion in any suitable manner.

The metal strip need not be the type shown in the figures just described, but it may be a simple U-shaped channel strip I4 as disclosed in Figure 4 wherein the parallel arms of the strip have inwardly curved lower portions I5 that extend towards each other and pinch the felt cushion and fabric cover into intimate relation to secure the parts together. The felt cushion may be provided with reinforcement, either fabric or rubber, in the form of a sheet 4a as shown in Fig. 4, and sponge rubber may be substituted for the felt shown in this modification.

In the structures last described, the metal strip is depended upon to hold or retain the covering in intimate contact with the cushion material, a simple example of which has been described in connection with Figure 1. 'I'he types disclosed in Figures 1 to 5 may be modified by uniting the fabric covering to the cushion material (either feli or sponge rubber), by the use of stitches or other securing means such as staples or the like. These securing means (stitches or staples) may be passed through the fabric covering and the cushion at a location back of the lower reach I 2 of arm I Il of the metal strip as shown at Iia in Figure 6. The application of securing means of this type will effect a saving in the covering fabric because it will be of less width so that the longitudinal edges of the latter will terminate adjacent the securing means as shown in Figure 6 and need not extend up inside the channel 8 of the metal strip as previously described.

In Figure 7 the securing means 3* (stitches or staples) are disposed outside the metal strip below the lower edge I3 thereof and the edge of the covering material nearest the edge I3 extends up inside or back of the latter so that it will protect the front face of the cushion from foreign matter. The securing means 3a in Figure 8 are disposed near the lower edge of the weather-strip close to the loop I of the cushion material and the edge of the covering fabric which is outermost when the weather-strip is mounted, extends up under the lower edge I3 of the metal strip so that the face of the cushion is'protected against atmospheric conditions and foreign matter.

In Figures 9 to 13 and Figures 19 to 24 the cushion material, either felt or rubber, is in the form of a flat unlooped strip either with or without reinforcement. For example, in Figure 9 the felt cushion I has the reinforcements l disposed within its body between the fiat surfaces thereof and in Figure 10 the reinforcement 4 is disposed upon one face of the felt cushion, while in Figure 11 the reinforcement is omitted from the felt cushion I. In Figures 12 and 13 the rubber cushion is shown respectively with the reinforcement on one face and with the reinforcement omitted. In all of these figures from Figure 9 to 13 the single ply of cushion material either with or without reinforcement is protected by the covering fabric 2 that extends along the opposite faces and around the lower edge of the cushion, and the upper edges of the cloth and the cushion are clamped together between the arms of the metal strip in a manner similar to the structure shown in Figures 1 to 5 .P inclusive.

In lieu of utilizing the beading II of the metal strip and the inwardly turned edge 9 of the other arm of the metal strip to retain the fabric covering upon the cushion, the covering may be attached to the cushion by the securing means 3a such as stitches or staples. These modifications are shown in Figures 19 to 24 with the exception of Fig. 22.

I-n Figures 19 and 20 the structures correspond with the structures shown in Figures 9 and 10 in that the reinforcement- YIl is respectively within the body of the felt cushion and at one face thereof, and Figure 21 corresponds with Figure 11 in that the reinforcement is omitted. Figures 23 and 24 correspond with the structures shown in Figures 13 and 12 in that the rubber cushion is respectively without reinforcement and is provided with reinforcement on one face. ric covering in Figures 19, 20, 21, 23 and 24 is not as extensive as that shown in the corresponding other figures and it is connected by the securing means to the cushion so that the edges of the fabric terminate slightly above the lower edge of the metal strip.

In the structures disclosed herein which employ securing means 3a such as stitches or staples to connect the covering fabric to the cushion, the back face of the cushion apparently is exposed between the lower edge of the short arm 9 of the metal strip and the upper edge of the covering fabric. This, however, is not detrimental because of the fact that this is as above mentioned, the back or surface of the weather strip and it will lie against and fit snugly to the door or window to which it is attached so that the cushion material is not exposed to atmospheric conditions or foreign matter when the weather-strip has been mounted and is in use. Should it be desired, the

covering fabric may extend-above the securing means 3 so that it may be clamped near its edges to the cushion by the metal casing in addition to being stitched or stapled. This is shown in Fig. 22.
